BACKGROUND: Non-ablative 1550-nm erbium-doped fractional photothermolysis systems (FPS) and 10 600-nm carbon dioxide fractional laser systems (CO(2) FS) have been effectively used to treat scars.
OBJECTIVE: We compared the efficacy and safety of single-session treatments of FPS and CO(2) FS for acne scars through a randomized, split-face, evaluator-blinded study.
METHODS: Eight patients with acne scars were enrolled in this study. Half of each subject's face was treated with FPS and the other half was treated with CO(2) FS. We used a quartile grading scale for evaluations.
RESULTS: At 3 months after the treatment, the mean grade of improvement based on clinical assessment was 2.0 +/- 0.5 for FPS and 2.5 +/- 0.8 for CO(2) FS. On each side treated by FPS and CO(2) FS, the mean duration of post-therapy crusting and scaling was 2.3 and 7.4 days respectively and that of post-therapy erythema was 7.5 and 11.5 days respectively. The mean VAS pain score was 3.9 +/- 2.0 with the FPS and 7.0 +/- 2.0 with the CO(2) FS.
CONCLUSION: We demonstrated the efficacy and safety of single-session acne scar treatment using FPS and CO(2) FS in East Asian patients. We believe that our study could be used as an essential reference when choosing laser modalities for scar treatment.
